Not necessarily. In fact, genetic variation between human populations is
many times less that that between chimp populations.

But we find fossil Homo (rudolfensis) from probably at least c 2.4 Ma (not
so long after the H/P split). And of Orrorin c 6 Ma it's impossible to say
whether it belong to H or to P. Besides, retroviral data suggest H might
have been absent from Africa between 4 & 3 Ma (CT Yohn cs.2005
"Lineage-Specific Expansions of Retroviral Insertions within the Genomes of
African Great Apes but Not Humans and Orangutans" PLoS Biol.3:1-11).

Certainly not: erectus had much thicker bones than all other primates,
living & extinct. Cursorials are lightly-built of course.
